Rancho Cucamonga, CA Soliciting & Door-to-Door: No-Knock Registry (2026)

Rancho Cucamonga Municipal Code backs up a resident's right to refuse uninvited solicitors by making it a violation for any permitted peddler, canvasser, or solicitor to ignore a No Solicitors, No Soliciting, or similar sign posted at or near the main entrance of a residence. To be enforceable, the sign must be legible and clearly visible from the approach to the front door, typically at a minimum size of 3 inches by 4 inches. This local enforcement supplements the federal Do Not Call Registry that covers telemarketing but does not apply to door-to-door activity. Religious and political canvassers have stronger First Amendment protections but typically still respect No Solicitors signs as a matter of practice; commercial solicitors who violate the sign rule can be cited under Municipal Code and have their solicitor permit suspended or revoked by the Finance Department. Residents who experience repeat violations or aggressive solicitors should call the Rancho Cucamonga Police non-emergency line at (909) 477-2800, note the solicitor's company name and badge number, and file a complaint with the Finance Department if the solicitor held a city permit.
